250,000+ New Users Through High-Volume, High-Deliverabilit Email Outreach
Overview
Maestro.io is a next-generation streaming platform built for creators, brands, and media companies — a more advanced and flexible alternative to legacy tools like Vimeo, Dacast, and Brightcove.
Although Maestro had spent years building a powerful platform, they faced a challenge shared by many growth-stage SaaS companies:
They possessed a massive dataset of users from competitor platforms…
…but no strategy, no deliverability infrastructure, and no system to turn those users into paying Maestro customers.
They approached us to help transform this dormant list into a predictable acquisition engine.
One year later, Maestro saw 250,000+ new signups, 80+ new users per day, open rates above 80%, click-through rates above 20%, and 100% deliverability across all campaigns.
This became one of Maestro’s most successful acquisition channels — built entirely from outbound email.
The Challenge
Maestro had a growth opportunity sitting in their database:
A large list of users from competing platforms including:
- Vimeo
- Dacast
- Brightcove
(And other leading live-streaming providers)
But they lacked the ability to:
- Reach out at scale without going into spam
- Warm up domains or inboxes properly
- Create messaging that resonated with streaming users
- Handle volume (20k+ emails/day) without deliverability collapse
- Build a repeatable engine instead of ad-hoc campaigns
They needed a way to safely and effectively contact tens of thousands of competitor users - daily - without harming their domain reputation or triggering spam filters.
The opportunity was huge.
The risk was equally huge if done wrong.
What We Did
We engineered a complete outbound acquisition system built specifically for large-scale SaaS user migration.
1. Built a Multi-Server Email Outreach Infrastructure
We deployed a high-capacity emailing framework that included:
5 dedicated outbound email servers
A mix of Google Workspace (Gmail), Microsoft Outlook, and custom SMTP servers
Multiple sending domains
Automated reputation balancing
Smart throttling to avoid spam triggers
This allowed us to safely send 20,000+ emails per day without any deliverability degradation.
2. Manual Warm-Up Strategy for Maximum Deliverability
Unlike normal warm-up tools, which can be slow and predictable, we built a hybrid warm-up system:
Manual warm-up by trained virtual assistants
Human-like engagement patterns
Replies, forwards, stars, labels, and thread interactions
Warm-ups using the actual templates intended for Maestro’s campaigns
This is why we achieved 100% deliverability — extremely rare at this scale.
3. Message Framework Tailored to Competitor Migration
We wrote high-converting email sequences specifically designed to get users to switch from Vimeo, Dacast, Brightcove, and others.
Messaging emphasized:
Simpler onboarding
Lower streaming costs
Superior analytics
White-label capabilities
Higher performance on live events
Faster support and success enablement
Result: Maestro’s value proposition connected immediately with competitor users.
4. Full Campaign Execution at High Volume
We managed:
- Daily sending operations
- Deliverability monitoring
- Inbox rotation
- A/B testing
- Real-time optimization
- Click and signup attribution
The system ran 7 days a week with near-perfect uptime and consistency.
The Solution (The System We Built)
What Maestro received was a complete outbound acquisition engine:
✔ 5-server dedicated outbound infrastructure
✔ Hybrid manual + automated warm-up system
✔ Human-like engagement to reinforce domain reputation
✔ Multi-domain email deployment strategy
✔ 20,000 daily outbound emails at scale
✔ 80%+ open rates

This became one of Maestro’s strongest high-volume acquisition channels.
